In 2012, James Zhou, Paul Grossinger, and Richard Bromham launched the MMGuardian parental control mobile app. Having experienced difficulties with their own children, the founders of MMGuardian created the app to give parents tools to protect their kids from the risks of smartphones and the internet.

MMGuardian has a variety of parental control capabilities that include the following:

Receiving comprehensive reports of Internet and app usage
Setting time limits for devices
Controlling apps, such as WhatsApp, SnapChat, Instagram, and PlayStore
Filtering web results and activating safe browsing
Tracking device location
Getting image alerts of inappropriate images saved on devices
Seeing real-time alerts of new app installments, location updates, and attempts to view blocked websites
Blocking text messages and calls
Monitoring text messages through keyword trigger alerts

MMGuardian is available on iOS and Android devices. You can pay for a single device or multiple devices with a family plan. Prices vary, and you must pay a monthly or yearly subscription fee; it is not a one-time cost. Parental control capabilities also vary by device.
